Hoola Bandoola Band is a Swedish progg group. One of the most prominent groups during the heyday of the Swedish progressive music movement, Hoola Bandoola Band was founded by Peter Clemmedson, Mikael Wiehe and Björn Afzelius, the latter two of whom served as primary lead singers, the sole songwriters, and guitarists for the group; their lyrics dealt chiefly with left-wing political commentary. Since their original disbandment in 1976, Hoola Bandoola Band has reformed for sporadic tours in the 1990s and 2000s
